Fig. 6From: Assessment of safety margin after microwave ablation of stage I NSCLC with three-dimensional reconstruction technique using CT imaginga, b One lesion was clearly seen in the lung window and mediastinal window, which was pathologically confirmed as adenocarcinoma by biopsy. c 3D reconstruction revealed the size and margin of the tumor (purple color). d, e 3 days later, CT showed no pneumothorax and pleural effusion, and the ablation zone was visible. f 3D reconstruction revealed the ablation zone and spatial relationships of the tumor (purple color). g, h 4 months after MWA, there was enhancement in the ablation zone (the white arrow), which was considered as recurrence. i The images of pr-ablation (c) and postablation (f) were fused and displayed as (i). Quantitative measurement shown the minimal ablative margin was < 5 mm (the red arrow)Back to article page
